TRAIN-ARRESTER.

Specification of Letters Patent.

Patented Sept. 29, 1908.

Application filed February 17, 1908. Serial No. 416,288.

To all whom it may concern:

Be it known that I, FRANZ CARL KilHNE, a subject'of the German Emperor,residing at Charlottenburg, near Berlin, in Germany, have invented acertain new and useful Train- Arrester, of which the following is aspecificatlon.

Rail-brakes are already known, with an arrangement of levers adapted tobe actuated by a suitable device for the purpose of simultaneouslycovering both rails with sand. Sand-tracks have also already been usedto destroy the momentum of trains.

The present invention resides in the device which will be hereinafterspecified in the claims, and which allows of producing a sand-track in areliable manner to stop, in

case of need, an entire train.

The apparatus is illustrated as a cross sectional diagram in the annexeddrawing.

1 represents the outlines ofthe cars, 2 the clearance outlines thereof.A section of the rails 3, proportional to the momentum of the train tobe stopped, is arranged in troughs 4 of angle-iron, which are filledwith sand to the height of the upper rail-head, and which do notappreciably impede a train traveling at normal speed. Receptacles 6hinged at 5 5 to the outer edges of the troughs alsocontain sand. Boththe said receptacles are connected by levers 7 to a weight 8 which isnormally held in an elevated position by a suitable device, and thereceptacles are held in horizontal positions while the weight is in itselevated position. The release of the weight causes the receptacles,however, to swing upwards into the positions indicated in the drawing bydotted lines, so that the sand is emptied into the troughs. trainarrives the empty receptacles must be swung back to their horizontalpositions, in order to provide the normal clearance.

Before the Various means may be used for lifting the weight and holdingit in its elevated position, for example a hydraulic cylinder orcompressed air cylinder 9, or an electro-magnet.

In case of need a lever 10 is actuated by a suitable device, for exampleautomatically by a train in the known manner, and actuates a controllingdevice in the conduit 11 so that the weight 8 is released and thereceptacles 6 are tilted. Reversal of the controlling device 12 causesthe weight-to be lifted again, so that the empty receptacles 6 return totheir normal positions.

What I claim as my invention and desire to secure by Letters Patent ofthe United States is:

1. A train arrester comprising in combination a railroad track, sandreceptacles hinged adjacent to said track and means for tilting saidreceptacles towards the rails for discharging sand thereon.

2. A train arrester comprising in combination a railroad track, troughscontaining the rails of said track, sand receptacles hinged adjacent tosaid track and means for tilting said receptacles towards the rails fordischarging sand thereon.

3. A train arrester comprising in combination a railroad track, sandreceptacles hinged adjacent to said track and means for tilting saidreceptacles towards the rails for discharging sand thereon comprising aweight, a cylinder, a piston in said cylinder for upholding said weight,and means for releasing the fluld pressure from said cylinder.

In witness whereof I have signed this specification in the presence oftwo witnesses.

FRANZ CARL KUHNE.
